Application filed April 9 1901.

To all whom. t muy concern:

Be it known that I, LEoN CONSTANT HENRI CHARRIER,a citizen of theRepublic of France,

and a resident of Vendme, Loir-et-Oher, in the Republic of France, haveinvented certain new and useful Improvements in Wood- Carving Machines,of which the following is a specification.

This invention relates to wood-carving machines of the kind described inPatent No. 553,393, granted to L. C. II.' Charrier.

The object of this invention is to provide an improved constructionofsuch machine wherein the various operations are performed in a moreeliicient manner with great certainty and in such manner as to increasethe A output of the machine. .To this end and according to my inventionI provide the. machine with a suitably supported and counterbalancedreciprocating beam which is adapt-A n ed to carrya number ofindependently-Working tools and pressers, while the said beam alsoserves to actuate other tools carried by the frame of the machine abovethe table, and the said beam also acts in conjunction with a movablepart of the frame below the work to actnate other tools and also toautomatically clear said tools from the Work independent-ly of themovement of the beam in order to be `clear of the tools at the propertime. I also provide the machine with mechanism adapted to so coact withthe other parts of the machine that the work is fed with greater easeand accuracy.

I will now describe the improved machine with reference to theaccompanying drawings, in Which- Figure lis a front elevation of thecomplete machine. Fig. 2 is an end View looking from the left. Figs. 3and 4 are cross-sections of Fig. l, respectively ou lines A B and O D, EF G II. Fig. 5 is also a section of -part of this figure on the line XY. Fig. 6 showsa modified arrangement for actuating the side tools.Figs. 7 and 8 are enlarged views ofthe feed mechanism shown in Figs. land 2, and Fig. 9 shows one kind of carved molding produced by themachine. Fig. l0 is an end view of the transverse carriages andWork-table. Fig. 1l is an enlarged detail elevation of the tool-4holders T5, and Fig. 12 is an elevation of the and-slot connection.

same-looking from the direction of the arrow in Fig. 11. Y

A is a base-plate,ol` cast-iron,upon which the machine rests.

AO A are standards connected by a longitudinal bar A2 at their upperends, which serves to keep them parallel. A3 is a smaller standard orbracket iixed to the base-plate and connected by a stay-piece A4 to thestandard A.

D is the reciprocating beam, of cast-steel or other suitable metal,which receives a reciprocating motion from disks E E through suitablecross-heads F F, the said cross-heads Vhaving transverse guides f, inwhich slide blocks e, carrying the crank-pins e and e. The cross-headsare connected to the beams D by side rods j2f3. Upon the maindrivingshaft l is fixed a toothed wheel 1A, which gears With atooth-wheel lb upon the shaft 2. In gear with 1b is the tooth-wheel l,which is fixed on the shaft 3. Upon the shaft 3 are keyed thecrank-disks E E', which are connected to the lreciprocating beam D bythe. side ro'dsf2f3. In operation the rotation of the driving-shaft lcauses the beam D to reciprocate.

The beam D carries the tool-holders T2, T3, and T4. The tool-holders Tand T5are guided upon the standards A0 A and are actuated from the beamD, the one T. by connectinglevers G G, the lever G being pivoted atg tothe beam and at g' to the frame, While the lever G, which yis connectedto the tool, is also connected to the lever G at g2 by a pin-I This toolserves for impressing or indenting certain parts of the work, and theholder T is adj usted as to position by slides and set-screwsg3 g4. VThetool-holder 'l`5 isactuated throughthe 1evers H and rods H H?, the leverbeing cen'- tered at one end, as at h, to a bracket h upon the frame A0.In operation the tools in holders T2 T3 are brought down onto themolding to be carved by the descent of the beam D, and tools in holdersT T5 are actuated by the same downward movements on the beam through thelevers G G and levers H Ij-I H2, respectively. The tool-holder T2 iscarried by a part I, which is adapted to slide in a suitable guidewayinbeam D and is made :2 4 'marre adjustable to the work by means of ahandscrew I'. The tool-holder T3 comprises a chuck adapted to be rotatedat a high speedsay fifteen hundred to two thousand revolutions perminuteand is driven by a pulley J on the main shaft 1, which isconnected by a handy" (see Fig. 4) with a pulley L7'2 on thetool-spindle, the band passing over idle pulleysj3j4. This band j' iskept at a constant tension and length during the movement of the beam Dby means of a bent lever K K', pivoted or centered at k on the shaft land at k2 to the beam D. This lever K K' is hinged at 7a2 to accommodateitself to the movement of the beltj', which is of round section.

Referring now to the tool-holders T'4 T4, (shown clearly in Fig. 1,)these are carried by bell-crank levers, which are pivoted at 4 't4 tothe brackets Z l, carried by and adapted to slide at Z2 upon a table L,which is actuated as hereinafter described. The holders T4 T4 extendthrough the machine, and the tools t t are attached at t3 t3.

In operation the descent of the beam D act-s through connecting-bars tto rock the bellcrank levers t0, carrying said holders T4 T4 upon thecenter t4, and so cause the tools t t to receive a curved motion forcutting longitudinally convex portions of the Work. The dimensions ofthe curves are determined by the position of the tools in regard to thecenter t4 about which they turn. In order that these tools may beproperly cleared from the work, so as to allow the same to be fedforward at the proper time, the tableLis adapted to receive an`intermittent vertical reciprocating motion independently of the beam D,this motion raising the centers t4 and the tools from the work at theproper time. (See Fig. 3).

The table L is operated by a bar L', reciprocated by a cam L2 through apin or friction wheel L3. The bar L is slotted, as at L4, so as to passover the shaft 3, which serves to keep the bar L vertical duringitsmovement.

In operation the table L is raised by the bar L' and the cam L2 on theshaft 3 immediately after the tools in the holder T4 have made theircuts, and the table is lowered by the same means just before these toolsagain come into operation. '[he tool-bolder T5 is mounted on a carriageM, adapted to be adjusted in three directions-namely, transversely,longitudinally, and verticallyby sliding parts 'm3 m4 m5, respectively.The part m5 is guided vertically in the standards A0, and the part m3 istransversely adjustable in guides formed in part m5 and carries guidesm4, by which the tool-holder is supported, so as to be longitudinallymovable. 'lhe said holder carries tools t5 155, which are in the form oftwo sectors. The sectors are centered at 'm m on T5 and are connected bypins m' to a sliding part H3, said pins m traveling in a slot m4 on thepart H3. The sliding part H3 is connected by a pin H4 to the lever H2.In operation on the descent of the beam D the sliding part H2 is causedto de'- scend by the levers I'I I'I II2, and thereby the tools L5 5 arecaused to turn on the pivots m m and make the cut G5, the tools servingto cut concave longitudinal portions of the work. Suitableguiding-slots, such as 'm2, are provided.

T6 and T7 are tool-holders which carry two horizontally-working tools.(See Fig.2.) The holders are rendered adjustable by handscrews N N, andto allow of angular adjustment of the tool the holders are pivoted at n,and held in position by a bolt n passing through slot 'n2 in a bracketn2. The holders and tools are moved to and from the Work by a bell-cranklever comprising short arm h5 and a long arm n4. The longer arm 01" ofthe bell-crank lever forms a connecting-rod actuated by a crank 2 on theshaft 2, and its shorter arm is connected to the tool-holder T6 by thelink n4, so as to reciprocate the same, While the motion is properlydetermined by a guiding-link n4), pivoted at a7 and pivotedA on thelower part of the frame, as at ns. One set of links and levers n4 a5 nmay serve to actuate both the tool-holders T T7.

Instead of the means shown in Fig. 2 I may employ any suitablearrangement of levers for imparting the required reciprocating movementto the tool-holders T T7.

Referring now to the coperating mechanism for feeding the work to themachine, as shown in Figs. l and l0, O O are two carriages mounted inthe standards A A0 and having a vertical motion, being actuated by meansof screw-spindles 0, driven by bevelgear o and shaft o2, said shaft 02being provided with a hand-wheel 02 for adjusting the position of thecarriages O O.

P P are transversely-movable carriages, which are supported upon thecarriages O O' and move together therewith. Upon the carriages P P ismounted a table Q, of cast-iron or other suitable material, upon whichthe molding or work moves or rests. This table is fixed to the carriagesP P', so that.by the adjustment of the carriages O O' it is possible toadjust the height of the table in regard to the tools, so as to suitmoldings of different dimensions. The tools always work, as described,at or about the sameheight.

R is a feed-bar sliding With slight friction or on rollers within theunder side of the table Q. This bar R is provided at each end with aframe o", which supports and guides claws or gripping-plates S S'. Thelower plate S' is provided with a slot S40.

s is a pinion provided with an eccentric-pin SS, adapted to work in slotS10.

u is a toothed quadrant mounted on a pivot u and engaging the pinion s.

tu* is a beveled pinion carrying an arm u2, which is connected to anextension u of the quadrant u by a link u.

a4 is a beveled pinion engaging with pinion ug and carrying arm I11.5.

V is a longitudinal bar which is connected IOO IIO

by'a pin to the arms a5 a5 at both ends of the table. This bar isprovided at its center with aslot or groove V, arranged so as to allow'a vertical movement of the bar V when the table Q is raised or lowered.The horizontal bar V is adapted to receive a to-and-fro motion from abell-crank lever V2, actuated through a connecting-rod V3 from a camdisposed, but not shown, on the shaft 2.` Upon the same center as thepinion s and turning with it is a brackets, which is connected to thebell-crank levers s4 by the links s and s2. The bell-crank lever s4 isconnected by the link s2 to the arm S12, which turns on the pivot S13.The armV .s1-2 is provided with aneccentric-pin S7, which works in aslot s2 in the sliding part of the upper jaw S.

In operation the bar V receives a horizontal reciprocating motionthroughfthe crank-` lever V2, the rod V3 and cam on shaft 2. (Notshown.) This movement of the bar V actuates the arm or lever a5 andcauses the pinions a4 u2 to partly rotate on their respective pivots.The lever u2, mounted on the pinion u2, is thereby moved, and with itthe link u and quadrant u. The motion of the quadrant u causes thepinion s to rotate, and the eccentrie-pin ss, mounted thereon, raisesthe lower gripping-jaw S. The movement of the pinion s also actuates thearm S12 through the links and levers s S5 s2 s4 s2, thereby causing theeccentric-pin to travel in the slot sg and lower theuppergripping-jaw S.On the completion of the revolution of the cam on shaft 2 the jaws S Sare opened bythe reverse action of the levers described. Y

When the jaws S S are tightened onto the work, any horizontal motiongiven to theV bar R will cause the work to travel forward. Thehorizontal motion of the bar R is produced by means of a lever W, Figs.1,7, and 8, pivotedat W and having at its lower end a roller W2,actuated by a cam-like plate W3 of suitable shape, mounted on and drivenby shaft 3. When the claws S S' are released, the return movement of thefeed-bar and other parts of the feed mechanism is effected by a spring.or counterweight X. (Shown by dotted lines in Figs. l and 7.)

The forward movement of the lever W is determined by the stop W4,- whichis made adjustable or is adapted to be replaced by others of differentdimensions. By thus determining the motion of the lever W the length ofthe feed is adjusted to set the particular work in the machine,

, In order that the work may be efficiently held while the tools areoperating, several pressers YY Y2, having springs, are provided. Thepressers Y Y Y2 consist of a spindle or rod Y6, passing up through holesin the reciprocating beam D and top frame A2. The said holes areenlarged and provided with a screwed collar Y7 and screwed sleeve YS.The spindle or rod is formed with a shoulder, as at Yf, between whichand the screwed collar Y7 a spring Y10 is fitted. In operation, as-

The operation of the machine is as followsr.

The strip or molding to be carved is fed into the left-hand side ot' themachine. The jaws S S grip the molding and feed same forwaxgd over thetable-Q, the bar R lmoving with the feed-jaws at both ends. clamped bythe presser and acted upon successively at each interval between themove-v ment of the feed by the tools T to Tsand the intermediate sidetools TG'T7. As soon as the The moldingis then 'Y molding has reachedthe last- `tool T5 the operation will take place at one time, although`on differentlportions of the work, the latter passing away from thetoolT5 in a finished state.' i v The means by which the tools areactuated having been already described l will for clearness describe theaction of the successive tools in carving the pattern shown in Fig. 9,although the said tools are of the same shape and'work in the samesuccessive order as those described in the previous patent referred to.Taking the tools in rotation, T makes a vertical cut, (marked 61,)thenT6 cuts the V-groove 66. T2 then cuts the pattern by Vertical lines62. The side tool T7 makes a horizontal cut, so as to remove the part 67previously cut vertically by the tool T2. T2 then drills the holes 63.v2f t then cut the convex parts 64 64. T5 finishes the pattern bycutting out the slightly-concave parts 65. 1
